The Washi Z 400 is a black and white film. It is based on a film for aerial photography and is wonderfully suited for high-contrast B&W images. The Washi Z 400 film is panchromatic and has a sensitization up to 750nm.
Like the Rollei Retro 400S, it is cast on a polyester base.
The Washi Z 400 is only available for 35mm cameras. The cartridge does not have DX encoding, so it can only be used in cameras that offer the possibility to set the ISO value themselves. The sensitivity of the black and white film is specified as ISO 400.
It has to be developed in a real black and white developer. It is offered by a French supplier.
